Yes, there are several people from different countries around the world on this forum. All it takes is the ability to read and write English and an interest in plants of all types.
I live in what is called the dry tropics, we have a distinct wet and dry season. During the wet season, summer, we get almost daily monsoon type rains. During the dry season, winter, there is little measurable rain except for the 'little monsoon' usually in late January. It lasts about a week and then we return to dry until June. We are at 20° lat and southern Florida is 25°lat, so we are about equal to the middle of Cuba. I'm 20mi inland from the Gulf of Mexico so there is also an ocean effect but I'm far enough not to have to worry about salt water or air. This peninsula is solid limestone and the ph of the soil and water are very high due to that. Those are the things that I have to deal with in gardening, cold is not a factor except that some plants require it and those don't grow well here.
Welcome to ATP, I think you will grow to love it here. It's always difficult to leave a spot that you have spent a lot of time on, it feels like home. However, if you invest that time here I think you will find yourself a new home.
